DD CLC/TS 50433:2005 Guidelines for paving the way for broadband "Broadband, 25 Mbit/s and more for All"

This Technical Specification is intended to provide general guidelines for improving metropolitan edge and local access networks in order to accelerate their growth in capacity and further enhance the coverage of global broadband services. The purpose is to ensure smooth migration from today’s services to future services requiring very high speed transmission capabilities in all parts of the network, based  on typical household expected future needs.

The paper identifies different scenarios to enable modular and coherent networks evolution while maintaining necessary levels of interoperability. It also reviews existing standards, and provides a draft list of standards to be developed.

This paper globally addresses generalisation of optical fibre throughout metropolitan edge and local access networks, including reach into end-user connections.
